# commit 0644f186fc9d77bb5bd198369e59fb28927a3692
# Merge: 0871062 5c60300
# Author: Linus Torvalds <torvalds@linux-foundation.org>
# Date:   Thu Apr 26 16:36:11 2018 -0700

#     Merge tag 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mst/vhost
#     
#     Pull virtio fixups from Michael Tsirkin:
#     
#      - Latest header update will break QEMU (if it's rebuilt with the new
#        header) - and it seems that the code there is so fragile that any
#        change in this header will break it. Add a better interface so users
#        do not need to change their code every time that header changes.
#     
#      - Fix virtio console for spec compliance.
#     
#     * tag 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mst/vhost:
#       virtio_console: reset on out of memory
#       virtio_console: move removal code
#       virtio_console: drop custom control queue cleanup
#       virtio_console: free buffers after reset
#       virtio: add ability to iterate over vqs
#       virtio_console: don't tie bufs to a vq
#       virtio_balloon: add array of stat names
